For many practical SLE, the coefficient matrix (see Equation (1)) is Symmetric Positive Definite (SPD). In this case, the efficient a 3-step Cholesky algorithm [1-2] can be used. A symmetric matrix is SPD if either of the following conditions is satisfied: If each and every determinant of sub-matrix is positive, or.. If for any given vector ...

Step 3. The partial derivatives of the matrix is taken in this step and set equal to zero. Recall, is a vector or coefficients or parameters. Because the equation is in matrix form, there are k partial derivatives (one for each parameter in ) set equal to zero. The rules of differentiation are applied to the matrix as follows.
